Abstract
Abstract The present invention generally relates to devices for limiting the movement of hinged panels such as doors and more particularly to a door stop that can be mounted directly on a door hinge. The door stop comprises a continuous sleeve having a semi-cylindrical inside surface surrounding the hinge barrel and two contact surfaces to engage the hinge plate of a hinge to prevent the door from opening beyond a predetermined angle. Preferably, one contact surface has a greater surface area than the other contact surface. At least one end plate containing a pin aperture is attached to one end of the sleeve. The pin aperture is sized to receive a standard hinge pin shaft therethrough.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
A door stop for engaging a door hinge having a hinge plate and a hinge barrel, comprising: (a.) a continuous sleeve having a semi-cylindrical inside surface surrounding the hinge barrel, a first end and a second end, the sleeve including a first contact surface for contacting a first hinge plate and a second contact surface to engage a second hinge plate; (b.) a first end plate connected to the first end of the sleeve, the first end plate including a pin aperture sized to receive a hinge pin; and (c.) a second end plate attached to the second end of the sleeve, and having an upwardly protruding nipple concentric with the pin aperture.
Claim 2
Dependent Claim
113 words
A door stop for engaging a door hinge having a hinge plate and a hinge barrel, comprising: (a.) a continuous sleeve having a semi-cylindrical inside surface surrounding the hinge barrel, a first end and a second end, the sleeve including a first contact surface for contacting a first hinge plate and a second contact surface to engage a second hinge plate; (b.) a first end plate connected to the first end of the sleeve, the first end plate including a pin aperture sized to receive a hinge pin; and (c.) a second end plate attached to the second end of the sleeve, and having an upwardly protruding nipple concentric with the pin aperture.
Claim 3
Dependent Claim
211 words
A door stop and door hinge having a limited range of motion, comprising: (a.) a first hinge plate having a plurality of spaced apart barrel segments attached to one edge, the hinge barrel segments having aligned bores for receiving an axially insertable and removable hinge pin therethrough; (b.) a second hinge plate having a plurality of spaced apart barrel segments attached to one edge such that the barrel segments are axially aligned and interdigitated with the barrel segments of the first hinge plate, forming a uniform, axially aligned hinge barrel, the hinge barrel segments having aligned bores for receiving an axially insertable and removable hinge pin therethrough; (c.) the hinge pin having a crown and a shaft; (d.) a sleeve having a semi-cylindrical inside surface surrounding the hinge barrel, a first end and a second end, a first contact surface for contacting the first hinge plate and a second contact surface to engage the second hinge plate; (e.) an end plate connected to the first end of the sleeve, the end plate including a pin aperture engaging the removable hinge pin; and (f.) a second end plate attached to the second end of the sleeve, the second end plate having an upwardly protruding nipple in axial alignment with the pin aperture.
Claim 4
Dependent Claim
211 words
A door stop and door hinge having a limited range of motion, comprising: (a.) a first hinge plate having a plurality of spaced apart barrel segments attached to one edge, the hinge barrel segments having aligned bores for receiving an axially insertable and removable hinge pin therethrough; (b.) a second hinge plate having a plurality of spaced apart barrel segments attached to one edge such that the barrel segments are axially aligned and interdigitated with the barrel segments of the first hinge plate, forming a uniform, axially aligned hinge barrel, the hinge barrel segments having aligned bores for receiving an axially insertable and removable hinge pin therethrough; (c.) the hinge pin having a crown and a shaft; (d.) a sleeve having a semi-cylindrical inside surface surrounding the hinge barrel, a first end and a second end, a first contact surface for contacting the first hinge plate and a second contact surface to engage the second hinge plate; (e.) an end plate connected to the first end of the sleeve, the end plate including a pin aperture engaging the removable hinge pin; and (f.) a second end plate attached to the second end of the sleeve, the second end plate having an upwardly protruding nipple in axial alignment with the pin aperture.
